To all 'whom t may concern.'

Be it known that we,- JOHNl W. S'IINE and JOHN E. STINE, citizensv of the United States, residing in the cityl and county of San Francisco and State. of California, have invented new and Hose-Couplings, of which the following is a specification. 7 A

This invention relates to a hose coupling.

t is the object of this invention to provide a hose coupling which is simple in construction, economical in manufacture, and which can be easily and quickly applied.

Another object is to provide a hose-coupling whichis adapted to be automatically locked against uncoupling, and which is so arranged that it will form a tight joint or union when applied.

A further object is to provide a hose coupling which is non-leakable, and which is suitable for use in connecting a hose to a hydrant or nozzle, and is adapted to be employed in high pressure water distributing systems. A i

The invent-ion consists of the parts and the combination and constructionv of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure l is a side elevation of the invention in its coupled position. vertical section on the line X-X, lFig. 1. Fig. 3 is a horizontal section onthe line Y-Y, F ig. l1 Figs. 4k and 5 are views in elevation in ,conjunction showing the invention in its uncoupled position.- Fig. 6 is a perspective view of the locking sleeve. Fig. 7 is a perspective 4view of the slotted tube on which the sleeve shown in Fig. 6 is mounted.

In the drawings, represents an interl nally threaded pipe connection which is adapted to be attached t0. a faucet or other externally threaded member. The lower end of the connecting member A is reduced in diameter, as at 2,fwhich reduced portion is threaded to receive the upper end of a tube 3. The connecting memberv A is further reduced below the threaded portion 2 to form a shoulder 4 which forms a seat for a packing ring 4, which ringis thus disposed in an annular groove formed Vby the outer wall of the lower end of the member A and the inner wall ofthe tube 3.

The lower end of the tube 3 has a hori- Zontally extending flange -5 formed thereon,

useful `Improvements in dlrection oppositel that of Fig. 2. is a sists. of an externally `tube 8 contacting wi Which flange is in position on the 3 before the latter is screwed on the 'member The sleeve 6 is milled on its outer sur'- face, as at grasped by the hand and turned on the tube 3, as later described. v

Formed in the` tube 3 is a peculiarly shaped continuous slot,

the flange 5, as shown in-F ig. .7. This slot leads parallel with the axis of the tube' for a short distance, as indicated at a, then turns at nearly right angles and extends approxiprovided as a means for rel 'taining a loose sleeve 6 tube 3, the sleeve 6 being placed on the tube to admit of its .being securely.

onev end of which- 'opens to the lower end of the tube, beneath matelyv half way around the tube, as' in.

dicated at b, this portion of the slot lv being disposedA at an angle in relation to the lateral diameter of the tube to form an inclined slot, the purpose of which will become apparent hereinafter.

The sleeve 6 is provided with a diagonal slot c which extends approximately half way around the sleeveand is inclined in a the diagonal slot b in the tube 3.'. The lower end of the'slot c in the sleeve 6 terminates in a longitudinally extending groove d formed by offsett1ng or raising the metal ofwhich the sleeve is formed at this point. The groove d opens to register with the slot a shown in Fig. 4, a lug 7 the flange 5 to limit the movement of the sleeve 6 in one direction and thus insure the alinement of the slot a and the groove d.

The above mentioned parts, when asin the tube 3, as

being formed on to the lower end of the sleeve and is adapted sembled as shown in Fig. 4, form the female member of our hose coupling'vand maybe permanently attached to a hose or hydrant.

The male member of the lcouplingcohthreaded memberB which is adapted to be hose or any internally threaded member. The member B has a ltubular extension 8 formed thereon, as shown in Fig. 5, which is designed to be contacting with the inner surface of the tube 3, the outer end of the th the packing ring 4', as'shlown in Fig. 2. Mounted on the tube 8 is a stud 9 which projects a distance from the outer face of the tube approximately equal to the combined thickness of the tube 3 and sleeve 6.

attached to a nozzle,l

inserted within the tube 3 with the outer surface of the tubular extension `8 closely v VIn connecting the tubular member to the entering the slot ZI in the tube 3.

i ofthe slot b acts as a we the stud 9.

" sleeve 6 will act as a wedge tovpermit'any applied t0 a; hose-coupling,

that it is equally female member ofthe coupling, the groove l in the sleeve 6 is first registered with the .slot a, in the tube 3, as shown in lug 7 on the flange 5 abutting against the Fig. 4, the

raised portion of the sleeve-6 'which bridges the groove d.y The tube 8 is then inserted in. thelower end of the tube 3; the stud 9 combined slot a and groove' d 4from thence into the diagonal The member 3 is then given a slight turn to therig'ht so as to cause the pin 9 to move upward gin' the diagonalslot b, thereb bringing the-outer end ofthe tube 8in c ose contact with..` the packing ring 4'." The inclined lower wall dgeon the .stud- 9 to retain thetube 8 in its innermost positionin .the tube 3. As the studi) is moved upward in the slot b' it `also travels upward in the diagonvl slot c in the sleeve 6, the latter turning on the tube 3. When the tube 8,has reached its uppermost position inthe tube 3 the sleeve 6 is turned a short "distance to the right so as to further wedge The slot cbeing disposed so as to cross the slot b as shown in Fig. 1, the

and passing movement 'of the'tube 3 on the tube 8,thus

securely locking the parts together.

To uncouple the coupling, -the sleeve 6 isturned to the left on the tube l3, thereby forcing the stud 9' down vthe inclined slots 'b-- soV that it will enter the slot a to permit of the removal of thetube 8 from the tube 3. -While we have .shown the invention' as applicable for use as a pipe coupling in connecting lengths of pipe, or v it may be employed in coupling or joining together any other members inwhich it what we claim and desire is ounddesirableto make a detachable connection, such, for instance, as in electric-light socket constructiomand similar devices.

Having thus described our invention, K b to secure by Letters-Patent, is'--'` 1. 1n a coupling of the character Ide,
